AIM: To study the roles of Toll-like receptor 4 ( TLR4 ) and TLR4 activator lipopolysaccharide ( LPS) in colonic inflammation recovery .METHODS:Normal intestinal epithelial cells were cultured with LPS in vitro. The subgroups of the intestinal epithelial cells with differential expression of TLR 4 ( low, normal and high ) were construc-ted by the technique of lentivirus transfection .The cells with normal and high expression of TLR 4 were induced by LPS for 0 h, 2 h and 4 h.Inflammatory cytokines TNF-α, IL-6 and IL-8 in the culture supernatant were detected by ELISA .The mRNA levels of TNF-α, IL-6, IL-8, IL-10 and IL-1βwere detected by qPCR .The cell mobility was also monitored by wound healing assay .RESULTS:The protein expression of TLR 4 was significantly higher after LPS treatment than that in control groups of both cells with TLR4 normal and high expression (P<0.05).The inflammatory cytokines TNF-α, IL-6, IL-8 and IL-1βat mRNA and protein levels were also significantly increased after LPS treatment compared with control group (P<0.05).The protein levels of TNF-α, IL-6 and IL-8 between the 2 groups were also different with statistical sig-nificance ( P<0.05 ) .Higher mobility was observed in the cells with TLR 4 high expression compared to control cells . CONCLUSION:LPS induction might play a role in the activation of TLR 4-mediated inflammatory pathways by up-regula-ting the expression of inflammatory cytokines at both transcriptional and translational levels .

AIM To study the effects of polydatin on free radical induced rat cortex mitochondria injury. METHODS Fe 2++VitC system was used to produce ?OH. The mitochondria was isolated. Mitochondria membrane fluidity, swelling and contents of phospholipid were determined to measure the function of mitochondria membrane. The activities of ATPase and Cytochrome C oxidase were determined to measure the ability of mitochondria energy metabolism. The activity of superoxide dismutase (SOD) and content of malondial dehyde (MDA) were determined to measure the ability of anti oxygenation. RESULTS ?OH resulted in severe neuronal mitochondria injuries and the injuries and the injuries was alleviated by Polydatin (content of 100,200,400 mg?L -1). The swelling of mitochondria was ameliorated, the decomposability of mitochondrion membrane phospholipid was decreased, the membrane fluidity of mitochondria was increased. Polydatin also significantly inhibited the decrease in SOD, Cytochrome C oxidase and ATPase activity and the increase in MDA levels caused by free radical. CONCLUSION Polydatin has a protective action against the rat neuronal mitochondria injuries induced by oxygen free radical. The mechanisms may be derived from scavenging free radicals, reducing lipid peroxides, and improving the energy metabolism.

Objective:To explore the relationship between rumination and depression and suicide attempts, and the mediating effect of rumination between depression and suicide attempts in adolescents with depressive disorder.Methods:Clinical interviews and questionnaires were conducted on 331 adolescents aged 11-18 with depressive disorders.Depressive symptoms were assessed with patient health questionnaire-9 (PHQ-9). Rumination was assessed with ruminative responses scale-10 (RRS-10), and Chinese version of the sociality module of MINI5.0 was used to assess suicide.SPSS 23.0 software was applied to descriptive statistics, Chi-square test, t-test, Spearman correlation analysis and hierarchical regression analysis, and the SPSS macro program PROCESS V 3.4 was used for Bootstrap mediating effect. Results:The incidence of suicide attempts in adolescents with depressive disorder was 53.78%, which was significantly higher in girls (59.48%) than that in boys (40.40%), and the difference was significant ( χ2=10.16, P<0.01). In contrast to the non-suicide attempt group, suicide attempt group had higher scores on PHQ-9((11.08±9.26) vs (14.43±7.49), t=-3.634, P<0.01), brooding ((10.76±3.89) vs (12.44±3.87), t=-3.926, P<0.01), reflection ((10.05±3.54) vs (11.20±3.33), t=-3.044, P<0.01) and rumination total score ((20.81±6.78) vs (23.64±6.42), t=-3.898, P<0.01). Regression analysis revealed that girl ( β=0.175, t=3.228, P=0.001), depressive symptoms ( β=0.168, t=3.082, P=0.002), rumination ( β=0.138, t=2.364, P=0.019) were risk factors for suicide attempts.Rumination played a complete mediating effect between depressive symptoms and suicide attempts (effect value=0.013, 95% CI=0.003-0.027). Depression symptoms significantly and positively predicted rumination ( P<0.01), and rumination significantly and positively predicted suicide attempts ( P<0.05). Conclusion:The incidence of suicide attempts was high in adolescents with depressive disorders.Depressive symptoms affect suicide attempts mainly through rumination.Clinicians should assess the rumination of adolescents with depressive disorders.In addition, clinicians should implement concurrent psychotherapy to adjust the cognitive response and reduce rumination, in order to improve the mental health and reduce suicide attempts.

In this paper, we present the results based on people’s experiences of sand sauna therapy at the Tavan Els Kidney Sanatorium in Mongolia. The sanatorium offers a type of balneotherapy through the application of thermally warmed sand and a combination of a healthy micro-bioclimate, a pure natural environment, and the preparation of fresh and healthy local foods. It’s function is to treat patients with chronic kidney glomerulonephrits through natural heated sand baths and other therapies. Sand sauna therapy involves an individual lying in a heated sand bath 8 to 20 minutes for adults and 7 to 15 minutes for child, and is performed twice a day (morning and afternoon) for 2 or 3 weeks once a year. The sand sauna treatment most likely affects the body by means of the sand’s high temperature and the presence of important biological and chemical elements. Our study was limited to the sand therapy and local conditions at Tavan Els kidney sanatorium. We recommend more collaborative scientific research on the effectiveness of balneotherapy for the treatment of chronic kidney disease (CKD).

Objective To assess the schistosomiasis transmission risk after flood disaster in Hubei Province in 2021, so as to provide a scientific basis for schistosomiasis prevention and control in corresponding areas. Methods The data pertaining to the endemic situation of schistosomiasis were collected from Hubei, including oncomelania snail distribution, and humans and livestock schistosomiasis infection. The warning water level and actual water situation were collected in corresponding water areas. The cumulative numbers of S. japonicum egg-positive people and cattle from 2014 to 2020, the distribution area of oncomelania snail in 2020, and the water levels from May 1 to August 31, 2021, were estimated and employed as parameters for classification of schistosomiasis transmission risk. The cumulative value of each risk index was calculated in each epidemic county (city and district) to comprehensively assess the risk of schistosomiasis transmission after flood disaster in each region. Results After the flood disaster in Hubei province in 2021, there were 2 counties (districts) at high risk of schistosomiasis transmission in Hubei based on the single risk index of fecal positive number. Based on comprehensive risk indices, there were 2 counties identified at grade 4 risk of schistosomiasis transmission. Conclusion After the flood in 2021, schistosomiasis in Hubei Province is mainly at low and medium epidemic risk. Xiantao City and Hanchuan City in Hanjiang River Basin are the two most seriously affected schistosomiasis epidemic cities. Flood disasters can increase the risk of schistosomiasis transmission and epidemic, so the monitoring and control of schistosomiasis after flood should be strengthened to control the disease transmission to the maximum extent.

Objective To explore the association of (cardiometabolic index , CMI ) and ( lipid accumulation product , LAP ) with the prevalence of hypertension in adults in Pingshan District, Shenzhen, and to evaluate the predictive value of CMI and LAP for the prevalence of hypertension. Methods A cross-sectional survey was conducted, in which 1000 permanent residents aged 18-69 years in Pingshan District, Shenzhen were randomly selected as survey subjects. The data were collected using questionnaires, physical measurements and blood tests, and the relationship between CMI, LAP and hypertension prevalence was analyzed using logistic regression models. Results A total of 987 subjects were included in the analysis, including 471 (47.72%) males and 516 (52.28%) females, with an average age of 40.9 ± 11.1 years. Subjects of different genders were divided into groups Q1 to Q4 according to quartiles of CMI and LAP, and the prevalence of hypertension increased with increasing levels of CMI and LAP in both men and women (P for trend < 0.001). Logistic regression analysis revealed that after adjusting for variables such as age and occupation, the OR for hypertension was 1.251 (1.025-1.526) and 1.685 (1.001-2.836) for men and women, respectively, for each standard deviation increase in CMI; the OR for hypertension was 3.519 (1.343-9.222) for men in the Q4 group, compared to the CMI subgroup Q1. For each standard deviation increase in LAP, the ORs for hypertension were 1.355 (1.089-1.686) and 1.825 (1.023-3.254) for men and women, respectively; compared to LAP subgroup Q1, the ORs for hypertension in the male Q3 and Q4 groups were 2.554 (1.103-5.909) and 5.322 (2.393-11.834), while the OR for hypertension in the female Q4 group was 2.906 (1.096-7.703). ROC analysis revealed that the area under the curve (AUC) for CMI, LAP, and BMI was 0.671, 0.704, and 0.702 for males, and 0.660, 0.722, and 0.697 for females, respectively. The AUC for LAP was greater than that for CMI for different genders (P < 0.01). Conclusion The greater the CMI and LAP values in adults in Pingshan District, Shenzhen , the higher the prevalence of hypertension. CMI and LAP have certain values in predicting the prevalence of hypertension.
